  • This application relates generally to communication systems, and, more particularly, to wireless communication systems.
  • SMS Short message service
  • 2G mobile switching centers
  • 3G third-generation
  • SMS services may also be provided by packet switched (PS) systems using Non- Access Stratum (NAS) signaling.

  • a 2G/3G communication system may include both MSCs that can support SMS messaging over CS connections and serving GPRS support nodes (SGSNs) that can support SMS messaging over PS connections.
  • SGSNs serving GPRS support nodes
  • User equipment can be configured to attach to CS networks, PS networks, or both.
  • GPRS handsets in a 2G/3G system can attach to both the CS and PS networks when operating in mode A or mode B, and when a GPRS handset is operating in mode C the handset can attach exclusively to either a CS or PS network at one time.
  • User equipment operating in modes A or B can register for either PS services via the PS network or combined PS/CS communication sessions that involve both the PS network and the CS network. Some embodiments of the user equipment can therefore request both CS and PS services, in which case network resources are allocated in both CS and PS domains and SMS messaging can be offered through either domain.
  • User equipment may also include machine type communication (MTC) devices.
  • An MTC device is defined by the 3GPP TS 22.368 as user equipment equipped for Machine Type Communication.
  • An MTC device can be a wireless communication device (e.g., a smart phone, a laptop, or a tablet) with an MTC application installed on it or the MTC device can be a device that is specific for an MTC purpose and communicates wirelessly to an MTC server, such as a water meter or health monitoring device.
  • Machine type communication is a form of data communication that involves one or more entities that do not necessarily need human interaction.
  • a service optimised for machine type communications differs from a service optimised for human-to-human communications.
  • An MTC device may use SMS services.
  • an MTC server may transmit triggers to one or more MTC devices using SMS messages. The triggers signal that the MTC device should begin collecting data. The MTC device can also transmit the collected data back to the MTC server, e.g.. using a PS connection to the network.
  • user equipment may connect to the network using PS and CS services or PS-only services.
  • user equipment may request PS services and SMS services that may be provided in either a PS domain or a CS domain.
  • the user equipment may be able to receive PS services via a connection to an SGSN in the PS domain and the user equipment may receive SMS services using either the connection to the SGSN in the PS domain or a separate connection to a mobile switching center (MSC) or visitor location register (VLR) in the CS domain.
  • MSC mobile switching center
  • VLR visitor location register
  • Providing the SMS services in the CS domain requires establishing a CS connection in addition to the PS connection used for PS services.
  • user equipment may conserve air interface resources by receiving both the PS services and the SMS services from the PS domain.
  • not all deployed SGSNs or networks support SMS via PS domain, e.g.. using NAS.
  • SMS-only plus SMS subscription should allow the SMS services be provided via CS domain in case SMS via PS domain NAS is not supported.
  • user equipment should be able to inform the network that it is only requesting CS services to support SMS services and the user equipment does not intend to register for any other CS services.
  • This type of registration is typically referred to as a request for "SMS-only" service, which can be provided using only signaling channels such as PS domain NAS or CS signaling channels.
  • SMS-only services can be provided by either the PS domain or the CS domain.
  • the network should also be able to inform user equipment during registration whether the network supports SMS via PS domain NAS and whether SMS services are provided by the SGSN or not. If SMS services are provided by the SGSN, no registration in the CS domain needs to be performed. Establishing a CS connection for user equipment may waste valuable network resources if the user equipment has requested SMS-only services and the network can provide the SMS-only services using a PS connection.
